[0031] Embodiment 1

[0032] like Figures 1-7 As shown, an upper gastrointestinal radiography simulation device proposed by the present invention comprises a fixing plate 1 and a supporting structure 2, wherein an oral cavity model 3 is movably connected to the side of the fixing plate 1, an elastic esophageal model 4 is fixedly connected to the bottom of the oral cavity model 3, a stomach model 5 is fixedly connected to the end of the elastic esophageal model 4 away from the oral cavity model 3, the stomach model 5 is fixedly connected to the fixing plate 1, a duodenum model 6 is fixedly connected to the side of the fixing plate 1 close to the stomach model 5, the duodenum model 6 is fixedly connected to the stomach model 5, a state simulation component is arranged between the fixing plate 1 and the supporting structure 2, the state simulation component comprises a connecting rod 12 movably connected between the fixing plate 1 and the supporting structure 2, and a ball 10 and a rotating rod 11 movably connected between the fixing plate 1 and the supporting structure 2, the fixing plate 1 can be manually tilted through the connecting rod 12 to adjust the upper gastrointestinal model on the fixing plate 1 back and forth between vertical and horizontal, the fixing plate 1 can be rotated through the rotating rod 11 to make the upper gastrointestinal model on the fixing plate 1 in a side-lying state, and the upper gastrointestinal model on the fixing plate 1 can be adjusted to any small angle range through the movable fixing plate 1 through the ball 10.

[0033] An adjustment component is provided on the fixed plate 1, and the adjustment component includes a slide plate 7 and a slider 15 fixedly connected to the side of the fixed plate 1. The oral model 3 can be extended and retracted up and down on the slide plate 7 through the slider 15. By manually moving one side of the slide plate 7, the slide plate 7 can be horizontally positioned on the fixed plate 1.

[0034] The slide plate 7 is slidably connected to the slider 15, and the slider 15 is fixedly connected to the oral model 3. The movement of the oral model 3 drives the slider 15 to slide in the slide groove 14 on the slide plate 7. The slide groove 14 is provided on the upper part of the slide plate 7, and the upper part of the slide plate 7 is symmetrically provided with a limiting groove 17, and the limiting groove 17 is connected to the slide groove 14.

[0035] The side of the slider 15 is movably connected to the limit rod 16, and a spring plate 18 is fixedly connected to the side of the slider 15 close to the limit rod 16. The spring plate 18 and the limit rod 16 are movably connected, and the limit rod 16 is slidably connected to the slide groove 14 and the limit groove 17.

[0037] Embodiment 2

[0038] like Figures 1-7 As shown, based on the first embodiment, an elastic U-shaped block 13 is fixedly connected to the upper portion of the support structure 2, a first serrated ring 20 is symmetrically fixedly connected to the inner side of the elastic U-shaped block 13, and a movable rod 22 is movably connected to the upper portion of the elastic U-shaped block 13. The movable rod 22 is above the elastic U-shaped block 13 and is in an active relationship with the elastic U-shaped block 13.

[0039] The side of the connecting rod 12 is symmetrically fixedly connected with a second serrated ring 21, and the two second serrated rings 21 are meshed with the first serrated ring 20. The connecting rod 12 is movably connected to the movable rod 22. By releasing the fixing effect of the elastic U-shaped block 13, the elastic U-shaped block 13 drives the first serrated ring 20 to be released from the second serrated ring 21.

[0040] One end of the movable rod 22 away from the first serrated ring 20 is fixedly connected to a support rod 24, and a fixed block 23 is movably connected to the outer side of the support rod 24. The fixed block 23 is movably connected to the elastic U-shaped block 13, and the fixed block 23 moves eccentrically on the support rod 24, thereby fixing the elastic U-shaped block 13.

[0041] The connecting rod 12 is rotationally connected to the rotating rod 11. One end of the connecting rod 12 away from the elastic U-shaped block 13 is fixedly connected to the annular block 25. The outer side of the annular block 25 is movably connected to multiple push rods 26. The push rods 26 are moved on the annular block 25 by holding them by hand.

[0042] Inside the annular block 25, a plurality of first springs 27 are fixedly connected. Each of the plurality of first springs 27 is fixedly connected to the push rod 26. When the push rod 26 is pressed, the first springs 27 are compressed, and the first springs 27 return the push rod 26 to the origin.

[0043] At one end of the rotating rod 11 close to the connecting rod 12, a plurality of limiting blocks 28 are movably connected. Each of the plurality of limiting blocks 28 is movably connected to the connecting rod 12. Inside the rotating rod 11, a plurality of second springs 29 are fixedly connected. The push rod 26 presses the limiting blocks 28, and the pressed limiting blocks 28 rebound to their original positions through the second springs 29. Each of the plurality of second springs 29 is fixedly connected to the limiting block 28.

[0044] On one side of the oral cavity model 3 close to the connecting rod 12, a sleeve 9 is fixedly connected. On one side of the rotating rod 11 close to the sleeve 9, a ball 10 is fixedly connected. The ball 10 is movably connected to the sleeve 9. The sleeve 9 is threadedly connected to the first bolt 8. The end of the first bolt 8 is movably connected to the ball 10. By rotating the first bolt 8 forward and backward, the restrictive effect and fixing effect of the first bolt 8 on the ball 10 can be released.

[0045] In this embodiment, through the above description, all kinds of molds in this device are made of transparent materials. The contrast agent is input through the input pipe on the oral cavity model 3. By pulling down the fixing block 23, the fixing block 23 moves on the support rod 24. The round block at the end of the fixing block 23 moves on the support rod 24 in an eccentric motion, releasing the restriction on the elastic U-shaped block 13, so that the elastic U-shaped block 13 drives the first serrated ring 20 to expand to both sides, releasing the engagement between the first serrated ring 20 and the second serrated ring 21. At this time, the fixing plate 1 can be lifted to drive the upper digestive tract on the fixing plate 1 to be horizontally adjusted. After adjustment, by pulling the fixing block 23 and using the eccentric axis, the fixing block 23 presses the elastic U-shaped block 13, so that the elastic U-shaped block 13 drives the first serrated ring 20 to be fixed on the second serrated ring 21. When it is necessary to adjust to the lateral lying state, hold the push rod 26 with the whole hand and press down the push rod 26;

[0046] Squeeze the limit block 28 to disengage the limit block 28 on the rotating rod 11 from restricting the connecting rod 12. The length of the push rod 26 is just such that the limit block 28 disengages from the connecting rod 12, so that the push rod 26 does not restrict the rotation of the rotating rod 11. At this time, by rotating the fixing plate 1, the fixing plate 1 drives the upper digestive tract on the fixing plate 1 to adjust the lateral lying state. At this time, release the held push rod 26 during the rotation process of the rotating rod 11. When the fixing plate 1 rotates to a suitable position, the second spring 29 is squeezed to drive the limit block 28 to be fixed on the connecting rod 12, thereby restricting the fixing plate 1. By rotating the first bolt 8, the fixing of the ball 10 by the first bolt 8 is released, so that the fixing plate 1 can be moved freely to make a small range adjustment of the fixing plate 1. A rubber block is fixed to the end of the first bolt 8 close to the ball 10, so that the first bolt 8 can increase the fixing effect on the ball 10.
